Connect Frontend Uploader with another plugin for adding products

I love your plugin – you have done an awesome job with it. But I’ve been having a bit of trouble and have not been able to find a solution for it for the last 10 days.

I’m in the process of setting up an Etsy clone at Fresheasel.com. Artists should be able to set up their store fronts on my site and consumers can directly buy from there. I’m using ‘Product Vendor’ Woocommerce plugin by Matt Gates (http://docs.mgates.me/wc-product-vendor/#Vendor_Dashboard) for this purpose. The plugin forces the artist to access the backend to Add Product.

But I want them to use a frontend. I tried to use you plugin to make a frontend that would connect with the Add Product page of the plugin’s backend, but I have not able to figure out how to do it.
